Chemistry - Real Gas Question with Solution | TestHub

The compressibility factor (Z)$=\frac{\mathrm{P}\times 22.4}{\mathrm{R}\mathrm{T}}=1$(for ideal gas)
$\left(\mathrm{Z}\right)=\frac{\mathrm{P}\times {\mathrm{V}}_{\mathrm{m}}}{\mathrm{R}\mathrm{T}}<1$(for real gas)
So$\frac{22.4}{{\mathrm{V}}_{\mathrm{m}}}>1$
or${\mathrm{V}}_{\mathrm{m}}<22.4$
